This invention relates to an improvement in governors and particularlyto centrifugal governors. These governors include springs attached atone end to a sleeve fixed to a spindle and at the other end to a collarlongitudinally movable on said spindle, the weights being thrown outwardby centrifugal force. In governors of this type, the weights are movedsolely by the springs, which are liable to torque, particularly when thespeed changes. It is necessary that these sprmgs should haveconsiderable flexibility, and, to avoid torque, recourse has been madeto using two or more springs for each weight.

The object of this invention is to provide a cage around said weights,to imp-art movement thereto and to prevent torque, and the inventionconsists in the construction as hereinafter described and particularlyrecited in the claims.

In the accompanying drawmgs:

Fig. 1 is a front view, partly in section, of a governor constructed inaccordance with my invention;

Fig. 2 is a side View of the same;

Fig. 3 is a sectional view on the line 33 of Fig. 1;

Fig. 4 is a sectional view on the line l4: of Fig. 2; and

Fig. 5 is a perspective view of the guidecage, detached.

In illustrating my invention, I have shown it in connection with agovernor forming the subject of an application filed February 3, 1930,Serial No. 425,562, but it Wlll be understood that the invention isapplicable to various types of governors.

The governor of the type shown includes a spindle and a sleeve 11 towhich springs 12 and 13 are connected, the other ends of the springsbeing connected with a collar 14. loose on the spindle, the collar 14being coupled with a controlling-mechanism. Connected with the springsare weights 15 and 16 and, as shown, these weights have parallel sidewalls 17 These weights are arranged in a guide-cage 18 formed with asleeve 19 which is fixed to the spindle 10 so as to turn therewith, andthis cage includes two box-like chambers 20 and 21 having parallel sidewalls 1930. Serial No. 439,601.

22 between which the weights 15 and 16 are arranged and in which theyare free to move radially but held against torque. Preferably, the twochambers will also be connected by a centrally-arranged flange 23 forreinforcement.

As the spindle 10 is turned, the cage and weights are turned with it,and as the speed increases, the weights move outward so as to draw thecollar 14: downward and through suitable mechanism control the devicefor which it is used.

The cages move the weights, which are thus guided in their movement,both laterally and vertlcally, and the weights so closely fit thechamber that they cannot be turned and hence prevent torque of thesprings.

I claim:

1. In a governor, the combination with a spindle, a sleeve fixed to thespindle, a collar movable on said spindle, springs connecting the sleeveand collar, weights mounted on said springs, and cages within which thesaid weights closely fit and may move radially but by which torque ofthe springs is prevented.

2. In a governor, the combination with a spindle, a sleeve fixed to thespindle, a collar movable on said spindle, springs connecting the sleeveand collar, weights mounted on said springs, and a guide-cage fixed tothe spindle and including a separate chamber for each weight and inwhich weights closely fit, whereby torque of the springs is prevented.

3. In a governor, the combination with a spindle, a sleeve fixed to thespindle, a collar movable on said spindle, springs connecting the sleeveand collar, weights having parallel side walls and mounted on saidsprings, and a guide-cage secured to said spindle and formed withchambers having parallel side walls enclosing said weights.

4. In a governor, the combination with a spindle, a sleeve fixed to thespindle, a collar movable on said spindle, springs connecting the sleeveand collar, weights having parallel side walls and mounted on saidsprings, and a guide-cage having two chambers arranged on opposite sidesof the spindle and formed with chambers having parallel side walls en- 7closing said weights.

5. In a governor, the combination with a r spindle, a sleeve fixed tothe spindle, a collar movable on said spindle, springs connecting thesleeve and collar, weights mounted on said springs and-having parallelside walls,

and a guide-cage formed with a sleeve fixed to said spindle, cages onopposite sides of said sleeve, said cages connected by a web, the

said chambers having parallel side walls between which the said weightsmay move.

In testimony whereof, I have signed this 5' IRVING M. CRAFTS;
